I had also problems installing the drivers from Webcam SumVision Panther. Could not find the CD in the pile of cd's I got. So try on the net and no driver has been found. Just stupid driverguide that want money. So It took me a while to search my whole room for the dammed CD
and I found it.
So to spare all the stress, I made for all of you an image.http://www.2shared.com/file/cLDX0u1m/sumvisiondriver.html
Try to mount this with Clonedrive:http://virtual-clonedrive.nl.malavida.com/mvdwn/364-windows
And it will work
